Abstract

The invention relates to the application of a biodegradable rolling emulsion composite in an aluminum alloy plate strip hot rolling technology. The biodegradable rolling emulsion composite is prepared from, by weight, 60-80 parts of vegetable oil and synthetic ester, 2-10 parts of at least one of oleic acid, triethanolamine and tall oil acid, 0-15 parts of at least one of petroleum sodium sulfonate, modified castor oil polyoxyethylene ether and alkylphenol polyoxyethylene ether, 0-5 parts of 12-14 alcohol, 0-10 parts of at least one of phosphite ester and phosphate ester, 1-5 parts of at least one of acid phosphate ester and isostearic acid, 0.5-2 parts of butylated hydroxytoluene, 0.05-1 part of octyl diphenylamine, 0.05-0.2 part of organosiloxane and 0.5-3 parts of at least one of methylene dimorpholine, iodo-n-butylproparglycarbamate and benzisothiazolones.

Description

Technical field [0001] The invention relates to the application of a biodegradable rolling emulsified oil composition in a hot rolling process of aluminum alloy plate and strip. Background technique [0002] In recent years, thanks to the development of my country's economy, the domestic metal processing industry has developed rapidly, and the consumption of metal processing fluid has been increasing year by year. At present, the non-renewable pure mineral oil type metal processing oil is gradually decreasing, and water-based metal processing fluid has become the mainstream product in the market, which also brings a series of environmental problems. The emulsified metal working fluid contains a large amount of mineral oil and has poor biodegradability. It is a material with a greater impact on the environment. These waste fluids have low recycling value and are difficult to handle. The mineral oil in it has poor degradability in the environment and is directly discharged to human...
